"I think they intended to put us out of business," said Jeff Clayborne, manager at Rocky Ridge Stone Company.

The Cumberland County Sheriff's Office says at least one person caused tens of thousands of dollars of damage to Rocky Ridge Stone Company in Crossville. His image was caught on surveillance video.

"This is our biggest season," Clayborne explained.

That number doesn't include the amount of money lost in productivity.

"We've had to call the customers and put them back," Clayborne said. "We told them it would be another 2-3 weeks."

The effects go beyond the damaged equipment.

"We've had to work late. We've had to put in long hours just to try and get the pieces of equipment put back together. It took away from our family time," Clayborne explained.

Managers said the vandal made it personal.

"If he had a grudge against the owners, or if he had a grudge against someone that works here, he made it personal not just to the owners but he involved innocent people that had nothing to do with it," Clayborne explained.

The vandalism is still under investigation, but production must go on.

"Start piecing stuff together and push forward," Clayborne said.
